Easier way to record VR video? (Gear VR/Cardboard)

Kite & lightning had their plugin for 360 degree stereoscopic video export, however my experience is almost 2 hours long, and their solution takes 40 seconds per frame.

So basically, is there an easier way to do this real time (or at least close to it)? The video doesn’t have to be perfect, and 180 degrees would work completely fine.
